Snowpack favorable for spring summer water supply

first_imgclick to enlarge The Lower Columbia Basin’s snowpack is in good shape, and that means good news for the region’s spring and summer water supply.The region has a snowpack 123 percent of normal for this time of year, according to the U.S. Department of Agriculture/National Resource Conservation Service National Water and Climate Center. That puts the local snowpack right along the state average of about 127 percent.“The reason (for) that is because it just isn’t melting yet and we keep adding to the pack,” said Scott Pattee, a water supply specialist with the U.S. Department of Agriculture’s Natural Resources Conservation Service. “But the normal peak is April 7, I believe it was. We’re getting well past that, and we’re just starting to peak now — maybe starting to roll off the other side.”The reason the snowpack is in such good shape is largely thanks to the “miracle March” we experienced last month, Pattee said.Until then, La Niña kept the jet stream bent north this winter, which kept the majority of the winter storms focused on Northern Washington and Southern Canada or offshore. That’s clearly explained when looking at Washington’s regions with the greatest snowpacks: the Upper Columbia and Spokane, which have 157 percent and 140 percent of normal snowpack, respectively.When La Niña, a cooling of water in the equatorial Pacific that affects global weather patterns, let up, that’s when the snow came to the rest of the state.last_img
